Ironruby core - Jan 2008 - Still plugging away at some simple IronRuby stuff

OK, I''m making progress.. Though my wife just got home, so this might
not last much longer ;-)

I am following the example at
http://ironruby.rubyforge.org/wiki/wiki.pl?ExecutingIronRubyFromCSharp

   NOTE:  I tried to be helpful and update that page with the examples
that were just posted to the list, but now the page includes this the
IScriptModule().SetVariable code - which doesn''t appear to be valid
anymore)

This is what I''m using instead and I get a MissingMethod error on
widget.  I''d try using this method (
scriptenvironment.ExecuteSourceUnit(rubyengine.CreateScriptSourceFromString(script)
);  ) but CreateScriptSourceFromString doesn''t appear to have a
signature for IScriptModule, or IScriptScope.

Thoughts?

           IScriptEnvironment scriptenvironment
ScriptEnvironment.GetEnvironment();
           IScriptEngine rubyengine =
scriptenvironment.GetEngine("ruby");

           string script = "puts ''Ruby and  '' +
widget.to_s + ''
together at last''";
           IScriptScope scope = scriptenvironment.CreateScope();
           scope.SetVariable("widget", ".Net");
           rubyengine.Execute(scope,
rubyengine.CreateScriptSourceFromString(script));
           Console.ReadKey();

IScriptModule is now IScriptScope from what I understand.  I couldn''t
figure out how to create or access local or instance variables, but
you can use a global.

I got this:


using System;
using Ruby;
using Ruby.Runtime;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
namespace RubyExample
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            IScriptEngine rubyengine
IronRuby.GetEngine(IronRuby.CreateRuntime());
           
IronRuby.GetExecutionContext(rubyengine.Runtime).GlobalVariables[SymbolTable.StringToId("widget")]
= ".NET";
            rubyengine.Execute(rubyengine.CreateScope(),
rubyengine.CreateScriptSourceFromString("puts ''Ruby and 
'' +
$widget.to_s + '' together at last''"));

            Console.ReadKey();


        }
    }
}

FYI, I just updated this page to fix the problem I caused last weekend.
